Lactic Acid is produced when a cell undergoes anaerobic respiration. In layman's terms, this is when a living cell is not receiving enough oxygen to produce the energy required to follow through it's functions. This does not necessarily mean you are not breathing correctly, but that lets say, you are running and require GREAT amounts of oxygen while your intake can supply only a limited amount. So, your muscles will switch to anaerobic respiration to produce the output needed with its limited amount of resources. The downside is, it produces Lactic Acid as well (but this is actually for our benefit because it helps produce the sensation of tiredness and muscle "ache" so that we calm down before we truly run out of oxygen to the point we pass out).
In yeast, anaerobic respiration causes the production of alcohol instead of lactic acid. This is why fermentation must be air tight so that oxygen cannot interrupt this process.

What conditions is lactic acid fermentation?
Simple answer:Under the condition of strenuous exercise with inadequate oxygen supply. ;DComplicated answer:When your muscle cells are asked to perform work at an easy relaxed pace they take in glucose, fructose or sucrose plus oxygen from the blood, and using the "Aerobic Respiration" method, they generate cellular motion energy without releasing lactic acid.Read more about that amazing process here:http://en.wikipedia.org/wiki/Cellular_respiration#Aerobic_respirationHOWEVER when your muscle cells are asked to perform strenuous work at an over-extended pace, (like your running away from a bear who wants to eat you). Then the oxygen becomes in short supply. There is not enough oxygen supplied by the lungs to increase output under the "Aerobic Respiration" method.So, the muscle cells, knowing that they will die if they don't produce more energy, have a Plan - B. They can create massive amounts of energy without oxygen with the drawback of creating lactic acid. But that's fine, they will clean up that mess later. They start using an "Anaerobic Respiration" method.Read more about that here.http://en.wikipedia.org/wiki/Anaerobic_exerciseThe muscle prefers to make energy using "aerobic methods", but in extreme situations, your muscle cells have a "turbo" option: "Anaerobic_respiration".This Scientific American Article answers your question:http://www.scientificamerican.com/article.cfm?id=why-does-lactic-acid-builAnd read this:http://en.wikipedia.org/wiki/Lactic_acid_fermentationAnswer #2:Your muscle cells will undergo lactic-acid fermentation (Creating cellular energy anaerobically) when there is not enough oxygen in the blood to create cellular energy in the preferred aerobic way.
Does the Krebs cycle start with pyruvic acid and yield lactic acid or alcohol?
lactic acid
What is the relationship between overexertion of muscles and the formation of lactic acid?
When muscles are overtaxed, the cardiovascular system can't supply enough oxygen to keep up with the needs of the tissue, and the muscle cells start fermentation to maintain a degree of energy production. The end product of the fermentation process (in this case) is lactic acid. (Pyruvate molecules are made from glucose - cf. glycolysis - but in the meantime, NAD+ coenzymes are reduced to NADH as a byproduct. In order for the process to continue, the NADH needs to revert to NAD+ and lose the hydrogen. The hydrogen is added onto pyruvate to form lactic acid).
Does your liver produce red blood cells in case of adults?
In case of the fetus, liver produces red blood cells. Red blood cells are produced by flat bones in case of adults. Given a challenge to produce the extra red blood cells, the liver may start producing red blood cells in adults also, as a last resort.
What takes place when there is not enough oxygen?
Many things happen on various levels and timeframes. Immediate effects will be a change in heart rate and breathing patterns. Longer-term effects can include muscle soreness. Lack of oxygen is called hypoxia. hypo means "less, under, low", ox means "oxygen", and -ia means "condition, state, or process". So hypoxia is a condition of low oxygen. Hypoxia causes the heart to beat faster in an attempt to push more oxygen to the body and its cells. On a cellular level, cells use oxygen to initiate their cycles. In other words, oxygen is one of the fuels (other than glucose) that drive each tiny cell's activities. Without any oxygen, cells stop functioning and can eventually die. This is called necrosis. Oxygen is needed by the mitochondria in order to produce energy. When oxygen supplies are low, the mitochondria of the cells make lactic acid instead. Lactic acid is the chemical most of us know as being associated with muscle soreness after exercise, especially when we've pushed exercise past our limits. What happens here is that your cells run out of oxygen, you run out of energy, and your muscles feel sore due to the lactic acid dumped into the muscle tissues by your cells. What the body's cells are pretty convincingly trying to tell you here is- stop exercising or we will die. Most of us indeed know when to stop and wait until our cells have recovered before placing high demands on our muscles again.
Why do you get a burring sensation in your muscles during exercise?
that burning sensation is the lactic acid building up in your muscles when your muscles produce lactic acid the start to burn thats why you get the sensation
When are reproductive cells produced?
Reproductive cells start to produce when you hit puberty.

Does football produce lactic acid?
beacuse when a footballer start a match he uses glucose and when thats glucose runs out and ATP runs out you have no more energy and latic acid starts to build up in your legs and you get cramp
How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?
5 minutes
How does lactic acid fermentation occur?
In humans, lactic acid occurs in aneroobic condition. when you do not have enough oxygen but you still need energy. Normally, oxidative phosphorylation occurs when there is enough oxygen. Instead a lack of oxygen requires--in humans of course to have this occur: NADH reduces lactate dehydrogenase to generate lacate. why this occurs is so your body can continue functioning. e.g if you were working out this lactic acid builds up. Normally enough oxgen would breakdown glucose through oxidative phoshorlyation. This lactic acid that builds up is actually toxic-- your body ends up converting some of that lactic acid to carbon dioxide and water.
What could be a chemical cause of fatigue?
Lactic acid is a by-product of fermentation. It was once believed that it causes muscle fatigue, but modern scientists are unsure if it reduces fatigue through increased intracellular calcium or increases fatigue through reduced sensitivity of contractile proteins to Ca2+.
Does the Krebs cycle start with pyruvic acid and yield lactic acid or alcohol?
lactic acid
Can bad circulation cause sore muscles?
If you are talking about bad circulation of oxygen, then yes, because the cellular respiration needed to make the energy necessary for moving muscles requires oxygen. And without that oxygen the cells in your muscles have to switch gears and start making energy through Lactic acid fermentation, which as the name points out creates an acid within your muscle cells, therefore causing a soreness. If we're talking about poor circulation of blood then the muscle cells won't be able to acquire enough oxygen to have respiration occur, causing the same switch to fermentation.

What are the three main sources of ATP that humans have?
Not sure I understand the wording of your question correctly but I hope the info helps. The 3 separate stages of the aerobic energy system are: Glycolysis, The Krebs Cycle and Oxidative Phosphorylation/Electron transport.
There are some cells that can not go through Mitosis In other words an organism can not make any new ones when the cells die Human nerve and muscle cells are examples?
cardiac muscle cells are one example of cells that cant undergo mitosis because they can't stop they're current action (for obvious reasons) so they can never start replication
